<p>PURPOSE:To achieve higher reliability by performing a winding at a large torque not through a slipping mechanism when a tape hub rotation load is large during an unloading. CONSTITUTION:Signals from both reel rotation sensors 2 and 3 are inputted beforehand and it is judged whether a reel is at rest or not in a mode of unwinding, quickly feeding a tape or the like to store whether a rotation load of a hub of a cassette is large or not into a microcomputer 1. When the reel stops during the operation of quick feeding, unwinding or the like, the rotation load of the tape hub may be too large to wind the tape when the the winding is done through a slipping mechanism. So, a winding torque is upgraded with a microcomputer 1 thereby preventing a trouble such as leaving a tape end.</p> |
